A group of British Columbia teenagers lured pedophiles to public locations, then appeared dressed as superheroes like Batman and the Flash and publicly shamed them. They also posted their encounters on YouTube. However, Canadian police have warned them that their unconventional crime-fighting tactics might put other kids at risk. Says RCMP Cpl. Mat. Van Laer,

Now you've aroused that male or that individual to a point where he's feeling that he might be meeting a child for a sexual encounter. Now if that person decides that he is going to go to a different school, or to a different meeting area or runs into another child, he may decide to act on that child instead.

The kids have retired their superhero identities and pulled their videos off YouTube. Still, British Columbia residents might want to keep an eye out for mysterious billionaire playboys and mild-mannered reporters in the years to come.
